SPECIFIGATIOFT forming part of Letters Patent No. 646,314, dated March27, 1900.

Application filed February 6, 189 9.

To all whom it may concern:

Be it known that I, FRANCIS MARION RITEs, a citizen of the UnitedStates, residing at Ithaca, in the county of Tompkins and State of NewY0rk,have invented certain new and useful Improvements in Governors; andI do hereby declare the following to be afull, clear, and exactdescription of the inventiomsuch as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates generally to improvements in governors orspeed-regulators, and particularly to improvements in governors of thetype known as fly-wheel or automaticcut-off governors, thoughthe'governor herein described may be adapted for the regulation ofthrottle-valves or the tripping-gear of a Corliss engine or any otherdevice for the operation of which governors are employed.

My invention consists in the novel combination and relative arrangementof movable weights and supporting devices therefor by which agovernor-weight structure utilizing in its operation both centrifugalforce and inertia and balanced as to gravity with respect to itssupports is produced, in the combination of swinging and rolling weightsin a governor, and in the novel combination, construction, andarrangement of the parts.

The objects of my invention are to improve and simplify governors, toprovide a weight structure composed of few parts, but balanced as togravity with respect to its -sup ports, and utilizing in its operationboth the centrifugal force or effect of its members and the inertia ofits members at times when the speed of rotation changes, to reducefriction in the governor, and to make it quick-acting, sensitive,reliable, not liable to derangement, and comparatively inexpensive.These objects are attained in the invention herein described,andillustrated in the drawings which accompany and form a part of thisspecification, in which the samereference-numerals indicate the same orcorresponding parts, and in which-- Figure 1 is an elevation, with aportion of the iiy-wheel or carrier broken away, of one form of governorcontaining two springconnected weights, one arranged to swing about asupport and the other to roll upon a guide carried by the carrier; andFig. 2 is a transgerial No. 704,670. (No model.)

verse section of the governor. Fig. 2 is a detail view of the supportingspring employed in the governor of Figs. 1 and 2. Fig. 3 is a viewsimilar to Fig. 1 of a form of governor differing from that of Fig. 1 inthat the spring which connects the weights is also connected to thecarrier and the weight which corresponds to the rolling weight of Fig. 1has a swinging movement, the effect of which is substantially the sameas the rolling movement of the corresponding weight of Fig. 1; and Fig.4 is a transverse section of the governor shown in Fig. 3. Fig. 5 is anelevation ofa governor containing a swinging and arolling weightconnected by a link, and Fig. 6 is a transverse section thereof. Fig. 7is an elevation of a governor the weight structure of which consists oftwo spring-connected weights supported by a single pivot-pin,whichweights by their relative motions produce fiexure of theirconnecting-spring tending to return them to normal position; and Fig. 8is an elevation of a governor both of the weights ofjwhich are rollingweights.

Referring now to the drawings, and first of all to Figs. 1, 2, and 2 1is a revoluble flywheel or carrier of suitable construction, and 2 is aweight, which for convenience may be termed a primary weight, secured tothe fly-wheel by a leaf-spring 3. The weight 2 has an arm 2 extendingacross the center of the fly-wheel and provided with two crossarms 2 and2, to one of which, 2", the spring 3 is secured. The other end of thespring is secured to a boss 1 of the fly-wheel. Opposite the mainportion of the weight 2 is another weight 4, which may be termed, forconvenience, a secondary weight and which is connected to the arm 2 by aleaf-spring 5, so that said weight is supported from the weight 2. Theweight 4 has a rolling contact with a guide 6 on the fly-wheel, and toprevent it from slipping on said guide instead of rolling thereon theguide is provided with a projecting stud 7, similar to a tooth of agearwheel, lying within a corresponding recess in the weight.

That side of the weight 4 which is to the left in Fig. 1 is the heavier,being provided the weight with the guide 6 and the center of rotation,so that the weight tends to roll upon the guide under the influence ofcentrifugal force.

The approximate positions of the centers of gravity of the Weights2 and4 are indicated in each case by the letters G G. The weight 4 is alsoprovided with an inwardlyprojecting arm 4 carrying an eccentric-pin 8.

The spring 3 when not under tension has the form shown in Fig. 2. InFig. 1 the parts are shown in the positions occupied when the fly-wheelis revolving and the engine cutting off steam early in the stroke. Thespring serves both as a means for supporting the weight structure insuch manner as to leave the parts thereof free to move under theinfluence of centrifugal force and inertia and as a means for resistingthe efiect of centrifugal force.

The operation of the governor is as follows: When the fly-wheel isrevolving, the weight 2 tends to swing outward, which tendency isopposed by the spring 3. The motion of the weight 2 from the position ofrest to the position required to maintain constant the speed of theengine is transmitted through the leafspring 5 to the weight 4, causingsaid weight 4 to roll along the guide 6, thus flexing the spring 5 tosome extent, and the centrifugal force of the weight 4 itself causessaid weight to roll upon the guide 6 still farther in the samedirection, still further flexing the spring 5. The motion of the centerof gravity of the weight 4 is in a direction substantially opposite tothe direction of motion of the center of gravity of weight 2, so that atall speedsthe weights are in substantial gravity-balance. The resultofthe motion of the weight 4 due to these combined influences is to movethe eccentric 8 inward, so producing a shorter cutoff in theengine-cylinder. If the speed of the fly-wheel rises, the inertia of thetwo weights causes them to lag somewhat, weight 2 swinging outward andweight 4 rolling along the guide 6, thus moving the eccentric inward andsupplementing the effect of the increased centrifugal force. If thespeed of the fly-wheel falls suddenly, the inertia of the weightsassists the centripetal action of the springs in moving the eccentricoutward. Placing the eccentric 8 upon the weight 4 has the advantage ofmultiplying, as to the eccentric, the angular movement of the weight 2;but the eccentric maybe placed on the arm 2 instead, as is the case inthe similar governor shown in Figs. 3 and 4. The weights 2 and 4 beingopposite each other and weight 4 being supported from weight 2, theybalance each other asto gravity partly or completely, as may be desired,the mass of the weight 4 being proportioned accordingly. In general itis not desirable to have weight 2 balanced completely.

In the form of governor shown in Figs. 3 and 4 the weight 4, instead ofhaving a rolling contact with the fiy-wheel, is carried by a leaf-spring 9, secured at one end to the arm 2 of the weight 2 and secured at theother end to the fiy-wheel. "Weight 2 is substantially the same inconstruction as the corresponding weight shown in Figs. 1 and 2, exceptthat its arm 2 carries the eccentric 8. In the operation of the governorthe weight 4 swings outward by flexing the spring 9, the path of thecenter of gravity being very nearly the same as that of the center ofgravity of weight 4 in the governor of Figs. 1 and 2. The operation ofthis governor is substantially the same as that of the former governor.

In the governor shown in Figs. 5 and 6 the primary weight 2 is pivotedto the fly-wheel, and the secondary weight 4, which is arranged to rollupon a guide 6 on the fiy-wheel, is connected to the arm 2 of weight 2bya link 13. The arm 2 has in its end a recess 14, into which the weight4 fits and which serves to hold said weight in place when the action ofgravity tends to pull it away from the guide 6. In this governor theweight 4 counterbalances the weight 2 as to gravity.

The springs 5 of the forms of governors shown in Figs. 1 to 4,inclusive, have a positive action tending to restore the governorweightsto their normal position independent of the springs In Fig. 7 I haveshown a governor in which such a spring as 5 is relied upon entirely torestore the parts to their normal position and to resist the effects ofcentrifugal force. It consists of two weights viz., a primary weight 2and a secondary Weight 4connected by a leaf-spring 5. Weight 2 ispivoted to the fly-wheel 1 at 10, and weight 4, which rests against thebeveled end of the arm 2 of weight 2, is connected by a link 15 to thefly-wheel, so that weight 4 is limited to motion in asubstantially-radial direction. In this governor motion of the weightsrelatively to each other due to centrifugal force produces flexure ofthe spring 5, so that the spring tends to bring the weights back tonormal position. This governor is claimed specifically in my applicationfor Letters Patent filed April 1, 1898, Serial No. 676,058.

Swinging weights may be dispensed with entirely and rolling weightsemployed instead. Such a governor is shown in Fig. 8, in which 16 16 aretwo weights having a rolling contact with the rim of the fly-wheel andconnected by leaf-springs 17. Each is weighted more heavily on one sidethan on the other, so that centrifugal force tends to cause them to rollupon the rim of the fiy-wheel. The weights are connected by arms 18 to asystem of levers 19, adapted to give movement to an axial stem. Thisgovernor and others employing rolling weights are illustrated,described, and claimed in an application for Letters Patent filed onMarch 8, 1898, Serial No. 673,069. i

The spring-supports for the weight structures of the governors shown inFigs. 1 t0 4, inclusive, are the mere equivalents of pivotal supportswith separate springs for opposing the effects of centrifugal force, andI do not limit myself to the use of either spring-supports or pivotalsupports in any of the governors herein described.

The governors are capable of many modifications without departing fromthe essential principles herein set forth, and I do not limit myself tothe particular construction and arrangement of the parts described andillustrated.
